when used as a sitting-chair; Fig. 2, a vie'wot' the same when used as a cradle 5 Fig. 3, a view of the same when used as a baby-jumper; Fig. 4, a view of the same when used as a cabinet; Fig. 5, a view ofthe socket and camshaped piece provided with the pin Fig.- 6, a sectional View showing the elevation of the second frame over the first frame.

In the drawings like parts of the invention are designated by the same letters of reference.

The nature of my invention consists in the.

construction of an improved chair for the nursery in such a manner that the same may be readily adapted to the various purposes hereinafter fully set forth.

To enable those skilled in the arts to make and use my invention, I will describe its construction and operation.

A shows a frame-work, which supports a secondary frame, B, the legs b b of which are made hollow and iit snugly over the legs t a of the frame-work A. The legs a cr are grooved, as at c, and the legs b b are provided with the pins d, which pins c1l slide in the grooves c and allow the frame-work B to be elevated the length of the grooves c.

C shows a platform placed about the center of the frame-work A, and D D are crosspieces for supporting the frame-work Q.

F are rods placed upon either side of the chair, below the seat E, which rods F have attached to their ends the plates of metal G, provided with the stops e, which pass through openings i i in the legs b b and legs et a, and are operated by means of the screw H and connections I, as hereinafter described. The screw H, inserted in the slotted piece f, is provided with the head g and nut h. To the head g are fastened the connections I. These connections I have connected to them the pins J J, upon which pins J J the rods F play freely.

K K show center pieces held to the frame B at each side by means of the pins L, which center pieces, K, are held about the center of the sides of the frame B, and are slotted, as shown at t', to allow them to move freely up and down upon the pins L. l

k k show rubber springs attached to the pins L and to the lower portions of the center able straps n, to which is attached the' saddle p,`and to which are attached the adjustable straps or bands q, connecting with the beltr. This ring R has riveted or soldered to itithe projecting pieces s and s', one of which, s, projects under the frame-work Q, and the other, s', over the same to secure the jumper to the frame-work Q. To this frame-work Q, at its forward end, is hinged the foot-rest P. This foot-rest P may be raised or lowered at pleasure, and when raised is held in position, as heretofore described. If desired, the foot-rest P may be detached.

l At the rear of the frame-work Q are placed the side pieces, t, provided with the sockets u, having the openings 'u and o', into which the pins w upon the cam-shaped pieces or, attached to the back S of the chair, are inserted.

E shows the seat of the chair placed upon the frame-work Q, and T the vessel placed upon the platform C when thc chair is used as a cabinet, in which case a second seat is employed.

My improved cha-ir for the nursery being thus constructed, its operation may be thus described. When desired to use the'chair as a sitting-chair, (sce Fig. 1,) the legs b b of the frame B are lowered over the legs a a of the frame A to their fullextent, the seat E is vplaced upon the fra nie-work Q, and the back S occupies the position shown, the pins upon the camshaped pieces .fr having been inserted in the openings v in the sockets u,while the footrest P'may be elevated, if desired. When desired to use the chair as a cradle, Fig..2, the seat E is placed upon the frame-work Q, the foot-rest P is elevated and held in position, as described hereinbefore, and the back S occupies a position not quite horizontal with the seat E, the pins w upon the calnshaped pieces :v being inserted in the openings 'v' in the sockets u. When used as a cradle, a vibratory motion is given to the same by means of the slotted cen ter-pieces, K, which swing freely upon the pins L. To use the chair as a baby-jumper, the frame B is elevated to suit the height of the child. The mode of elevating the frame B may be thus described: The nut h upon the screw H is loosened, and the connections I are thrown up out of the horizontal position they occupy to hold the frame in position. As the connections I are thrown out of the horizontal position, they cause the rods F (which rods F play freely upon the pins J, attached to the connections I) to turn, and the stops e to be thrown out of the openings in the legs b b ofthe framework B. The frame-Work B is then moved up over the frame-Work A to any desired height, and the nut h upon the screw H (the connections l having been previously depressed to their full extent, and the stops c having entered the openings in the legs b b) is tightened, and the frame-work B is held firmly in position. The seat E and foot-rest P are removed, and the metallic ring lt, provided with the saddle p and bands qand belt r, is placed upon the framework Q, the projecting pieces s and s', attached to the ring R, securing the jumper to the frame-work Q. The child is placed in the jumper and held there by means of the straps q and belt v', and the framework Q being attached, as shown, to the centerpieces, K, and side arms N, the jumper moves freely up and down from the movements of the child and the presence of the rubber springs 7c 7c, attached, as shown, to the pins L and the center pieces, K. While thejumper is in motion the feet of the child strike upon the platform C. My improved nursery-chair may also be used as a cabinet and as a high chair. In the former case (see Fig. 4) the seat E as well as the jumper are removed, and a second seat,W, rests upon the frame-work Q, the vessel T being placed upon the platform G. When used as a high chair, the frame-work B, with the seat E, back S, and foot-rest P, is elevated to any required height in the same manner as when the chair is used as a jumper, and held in that position, as hereinbefore fully set forth.

Having thus described my invention, what l claim therein as new, and desire to Secure by Letters Patent, is-

l. The use or employment of the secondary frame-work B, in combination with the frame Work A, when arranged and operated as herein shown, for the purpose specified.

2. lHolding the frame-work B in position when the same shall be elevated in the manner and by the means herein fully described.

3. In combination with the cam-shaped piecesprovided with pins, the sockets provided with the openings, for the purpose fully set forth.

4. In combination with the frame-Work Q, the use or employment of the slotted center pieces, K, and side arms N, for the purpose shown.

5. In combination with the same, the framework Q, operated as shown, for the purpose specified.
